Dell 1905FP

[ObsessionAudio]

recently I had replaced 3 bad caps on this monitor. Now upon powering up the display looks fine, all colors are good when its displaying the powersave logo, however when I connect it to a machine ( I have a good 60 some at my disposal) the display has a pinkish hue. Any suggestions?

Re: Dell 1905FP

Weak or no green. Are you on DVI or VGA?

If the VGA video cable detachable, change the VGA cable.

Does LCD have a color adjustment menu, check there.

It does it on both DVI and VGA, there is no color adjustment. the whole entire screen has a pink hue where i guess there should be white?

There are some LCD screens that only like 60Hz refresh from the video card.
That's all you need anyway because LCD screens don't have flicker like CRT screens.

The pink screened monitors were made special for women.
Thats what the FP stands for.

Re: Dell 1905FP

do a factory reset.
someone set a user color temp?
settings corrupted by bad caps?
if the no signal/check cable makes good white its got to be a color temp setting.

So my monitor has went from "woman edition" to "demonic edition". My pda cam sucks but here is a pic of what it is doing. The dell menu shows up fine but everywhere that you see red it should be black. I've got about 60 pcs at my disposal and probably somewhere near 100+ VGA/DVI cables.

This looks like either a video board malfunction due to bad semis or a cracked solder joint or an EEPROM malfunction.

Be sure to check the harness from the LCD to the video board and make sure that it's connected securely and none of the wires in the harness are loose or not making contact.

Re: Dell 1905FP

harness is good, what gets me is that it will display its built-in menus fine but the the colors go to hell when i connect it to any machine.

The crystal control board is removeable on the glass panel if it's the LGPhilips
light guide screen.
I have that board and will send it to you for the asking.
I'd send the whole panel but it's deeply scratched which is why it was not fixed.
I just don't know if the menues are generated here. I do see seperate B G R components connecting to both ribbons by removing shield cover, 3 screws.

Re: Dell 1905FP

In any case this is definately a logic problem it's not on the PSU.

Either the video board or yeah that little LCD control board mounted to the display (I forgot about that one).

I've seen on the new Dell LCDs the logic board and PSU are all in one.
